Frankel says: “Once you get good at two-handed rows do a single handed row and then try a powerpull. You’re reaching up as high as you can on strap and then lowering down like you’re doing row. It ends up being a one-armed row, but you’re adding this rotation so you’ll notice a long center line as you’re rotating around that plank and reaching up. The right side—the arm, the lat, and the back— are all getting worked at the same time. ”
